Abstract

The invention is related to a wavelength allocation scheme for a WDM (Wavelength Division Multiplex) equipment with a distribution of used optical channels that are arranged around a saturation channel in a way that the total spectrum of the optical channels is balanced independent from the number of equipped optical channels. <IMAGE>
